Claims.
Thisinvention relates to tank trailer vehicles landmore particularly to an internal frame struc- -ture for such Vehicles constructed and arranged .to act and serve both as a tank strengthening frame and as a chassis frame so that no exterior chassis frame is necessary.
One object of the invention is to provide a construction and arrangement of parts which will permit the maximum use of light materials such as aluminum or its alloys without sacrifice of strength and with a substantial decrease in A further object is to provide a frame, the members of which are so arranged that the wheels of the trailer may be positioned to so distribute the weight between the trailer wheels and the coupling pin at the nose as to increase the traction and braking effort of the rear wheels of the tow car. Other and further objects will be apparent from the following specification and claims.; n
In the accompanying drawings which illustrate one embodiment of the invention,
Fig. 1 is a side elevation of. a tank vehicle according to the invention, a portion of the tow vcar being shown in dotted lines;
Fig. 2 is a rear end elevation of the vehicle shown in Fig. 1;
Fig. 3 is a side elevation of the tank, parts be- \ing broken away;
Fig. 4 is a side elevation of the prow portion 'on a larger scale, parts being broken away;
Fig. 5 is a plan view on a larger scale ofthe rear portion of the tank, parts being in section; Fig. 6 is a similar view in section of the prow portion of the tank;
Fig. 7 is a. section substantially on line 'I-'I of Fig. 5, parts being broken away; y Fig. 8 is a section substantially on line 8-8 of Fig. 6;
. I Fig. 9 is a detail View showing the manner of prow portion 2 is curved upwardly as at 3 and the prow is provided at its extreme forward end i with a-coupling pin 4 by means of which the trailer is coupled to a tow car indicated in dotted lines at 5.
The tank structure comprises a frame enclosed ,end is closed by ahead 9 welded to the edge of (Cl. 28o-15) the wrapper sheet at Ill. The frame includes four rectangularly spaced longitudinal members I2 formed of aluminum, which extend the full length of the trailer. The preferred cross se'ction of the members I2 is generally T-shaped and as best shown in Fig. 10 the outer surface I3 of the head portion I4 is curved to conform to the curvature of the wrapper sheet to which they are directly welded. The members I2 are arranged relatively to each other as shown in Fig. 7, the web portions I5 being vertical. The flanges of heads I4 are not symmetrical, one flange I6 being relatively long and thin while the flange I1 is thick and short and forms a shoulder or abutment to which the edges of vertical plates 2U are welded. Plates ZIJ are formed of aluminum and are vertically corrugated. At the nose portion of the trailer the upper pair of members I2 are converged together in their original horizontal plane to a mitered welded joint I8 adjacent the upper end of, pin 4. The lower pair of members I2 are curved both upwardly and toward each other and then downwardly, as shown in Fig. 4, to a similar mitered and welded joint I9 adjacent the lower end of pin 4. The vertical position of the web portions I5 of the members I2 are maintained in a. vertical position throughout the length of the members and side plates are bent and shaped in the nose portion in conformity with the members I'2 to which they are welded.
The coupling pin is preferably of steel and is jointed to the tank frame by a plate bent y around and welded to the pin and riveted at 26 (see Figs. 4. 6 and 8) to the vertical webs of members I2. The wrapper 8 at the prow portion is formed by two side sheets 21 and top and bottom sheets-28 and 29 welded together at 3l), the flanges I6 of members I2 being bent to conform to the increasing curvature of the wrapper sheets. A l Wheel mountings are secured to the outside of the tank shell by means of metal pads 3I and 32 and brackets 33 riveted to the tank as at 34. .Springs 35 are connected by suitable shackles to the brackets 33 and the wheel axle is secured to the springs substantially as shown in prior copending application Serial No. 679,883, filed July 11, 1933, or in any other suitable manner. By connecting the springs to brackets secured directly to the tank, without the intervention of any framework the center of gravity is materially lowered, the tank extending downwardly between the wheels 35 as best shown in Fig. 2.
Inside of the tank the frame is provided with special bracing means, positioned directly over the pads 3I-32, by which the load and draft strains are transmitted and distributed to the frame members. The bracing structure comprises four columns 40, one over each pad assembly 3I-32. These columns as best shown in Figs. 5 and '7 are in the form of channels with their open sides facing outwardly. The vertical edges are provided with flanges 4I'to which the ends of the plate members. are welded. The closed sides of the columns are inclined to increase the width of the columns at the base. The opposing columns are connected by horizontal bracing members 43 and diagonal members 44 welded to anged gusset-plates 45 which are welded to the inner faces of the columns.
The tank is preferably divided into compartments by transverse bulkheads or partitions 50 formed of vertically corrugated aluminum 'plates' similar to plates 20. These bulkheads are all similar in structure, with the exception of the foremost bulkhead which is later described, and are constructed in three pieces. The central piece 5| is fitted between the vertical plates 20 and is welded at top and bottom to curved angle supports 52 which are welded to the tank shell 8. The sides of the central pieces 5I are bent at right angles, as at 53 in Figs. 5 and 9, and welded to the plates 20. Similarly side pieces 55 close the spaces between the plates 20 and the sides of the tank, the outer curved edgesbeing welded to curved angle members 56 which are welded to the shell while the inner vertical edges are bent at right angles as at 5l and welded to the plates 20. The plates 20 may be continuous from end to end of the tank but fabrication is facilitated by making them in sections and connecting the sections by overlapping and welding adjacent the bulkheads as indicated at 59, Fig. 9.
The forward compartment preferably includes a portion of the prow portion 2 and terminates at a bulkhead 60 positioned adjacent the rear ends of plate 25, see Figs. 6 and 8. This bulkhead comprises a central portion 6I welded at top and bottom to curved angle members 62 and 63 which are welded respectively to sheets 28 and 29, and at the sides to plates 20 as at 65, Fig. 6. The spaces between the plates 20 and sheets 2'I are filled by fitted plates 66 welded in place and the small openings above the upper members I2 are closed by the portions 61 of the angle member 62. At the point where the elliptical shape of the main body ends and the prow portion begins to converge, curved angle supports 'I0 are welded to the shell 8 and the members I2 to stiffen the structure at that point.
Free fiow of liquid within the compartments is assured by suitable openings 'I5 formed in plates 2U and drain holes 'I6 positioned as required in the webs of lower members I2 and the base of columns 40. Inlet openings TI, provided with suitable closures not shown, are provided for each tank compartment and any suitable discharge piping, not shown, is provided for discharging the contents of the tank. Housings of any desired form may be secured in position at the sides of the tank. As shown the housing comprises general utility cupboards 8l which are welded or otherwise secured to bands 82 which encircle the tank and are held in position by bolts 83 connecting their ends beneath the tank with the exception of the rearmost band, the ends of which are releasably secured by bolts 85 to outwardly extending flanges formed on the rear pads 3|. By loosening the bolts B3 and 85 to disconnect the ends of bands 82, the bands and housing structure may be removed bodily from the tank. The top 81 of the housing structure provides a running board. facilitating access to the tank through openings 11.
